Cystitis is inflammation of the bladder, most often from an infection, with burning on urination and frequent, urgent trips to the toilet. Mild cases sometimes resolve on their own, but cystitis often needs treatment with an antibiotic prescribed by a doctor. Below we explain the symptoms, what may help and when it is important to seek care. This article is informational and does not replace an examination.

Symptoms of cystitis
Typical signs are burning and pain on urination, frequent and urgent passing of small amounts, cloudy or strong-smelling urine and discomfort low in the abdomen. Sometimes there are traces of blood in the urine. There is usually no high fever — a fever points to a more serious infection.
What may ease it
Drinking enough fluids, rest and a pain reliever when needed may ease the complaints. Cranberry-based products and some herbal remedies are used by some people, but the evidence is limited and they do not replace treatment. Do not delay seeing a doctor for more marked or persistent symptoms.
Why an antibiotic is often needed
Bacterial cystitis is often treated with an antibiotic, which only a doctor can prescribe after assessment. Antibiotics are not taken from 'leftovers' of a previous course or without a consultation, because improper use leads to resistance and recurrences. Finish the course as directed by the doctor.
When you must see a doctor
See a doctor for pain in the lower back/flank, high fever, chills, nausea, blood in the urine, in pregnancy, in men and children, for frequent recurring episodes or if the symptoms do not improve. These signs may point to kidney involvement or a condition that needs examination and treatment.
Frequently asked questions
Does cystitis go away on its own?
Sometimes mild complaints subside, but bacterial cystitis often needs an antibiotic prescribed by a doctor. Waiting can lead to worsening or kidney involvement. For marked, persistent or recurring symptoms, do not delay a consultation.
Does cranberry help with cystitis?
Some people use cranberry products, but the evidence for an effect is limited and they do not treat an active infection. They may be an addition, but do not replace an antibiotic when one is needed. For symptoms of cystitis, consult a doctor or pharmacist.
Can I buy an antibiotic for cystitis without a prescription?
No. Antibiotics are dispensed by prescription and prescribed by a doctor after assessment. Taking an antibiotic without a consultation, or leftovers from a previous course, is dangerous and leads to resistance. The right choice and dose depend on the specific case.
How can I reduce the risk of cystitis?
Drinking enough fluids, urinating regularly and not holding it when you feel the urge, along with personal hygiene, may help. For frequent recurrences a doctor can assess the causes and suitable measures. This article is general and does not replace individual advice.
When is cystitis an emergency?
Seek urgent medical care for high fever, chills, back pain, nausea/vomiting or blood in the urine, and in pregnancy. These signs may point to a kidney infection, which needs prompt assessment and treatment.
